The object of the present invention is a machine for cutting meat, known in the sector as a slicing machine, particularly for foodstuffs and yet more specifically for fresh meats. Such slicing machine finds useful application in the processing and packaging of fresh meats, salted meats, cured meats and other foodstuffs.
In the prior art, a slicing machine comprises a frame, to which a support for the meat to be sliced is fixed. More specifically, the meat is constrained to the support cited in such a manner that a surface with contact with the meat is pressed against the frame at a striking surface.
The slicing machine further comprises a blade that is fixed to the frame, and has the function of cutting slices of meat.
During operation of the machine, the support slides with respect to the frame, pulling the meat that is pushed against the blade. In this manner, the blade comes into contact with the meat and cuts a slice of it.
The slicing machine known in the state of the art, has an important drawback.
In fact, the meat is pulled against a striking surface and, during the cutting stage, the slice tends to fray and curl up. To prevent this from happening, it is common practice to freeze the meat prior to cutting it. Disadvantageously, this causes an inevitable deterioration of the organoleptic properties of the meat intended for use as food.
In this context, the technical task underlying the present invention is to propose a slicing machine that overcomes the drawbacks of the known art as cited hereinabove.
In particular, an aim of the present invention is to make available a slicing machine that is capable of preserving the organoleptic and nutritional characteristics of the meat.
The defined technical task and the specified aims are substantially achieved by a slicing machine, comprising the technical characteristics stated in one or more of the accompanying claims.
Further characteristics and advantages of the present invention will become more apparent from the illustrative, and thus non-limiting, description of a preferred, but not exclusive, embodiment of a slicing machine, as illustrated in the accompanying drawings, in which:
a-3e are schematic, lateral sectional views of the slicing machine appearing in
With reference to the attached figures, 1 indicates a machine for cutting meat according to the present invention.
In the sector, the aforesaid machine for cutting meat is known as a slicing machine
This slicing machine 1 comprises a frame 2, whereto in particular a support 3 for the meat 18 to be sliced is connected. A striking surface 4 is associated with the frame 2, so as to support the meat 18 in cooperation with the cited support 3. In further detail, the meat 18 is blocked on the cited support 3 in such a manner that one of its contact surfaces is pressed against the striking surface 4. With reference to
The slicing machine 1 comprises a blade 5 to cut slices 19 of meat 18. In particular, this blade 5 is connected to the frame 2 and, during operation of the slicing machine 1, the blade 5 proves to be locked to this frame 2 so as not to move with respect to said frame 2. Furthermore, in the illustrated embodiment, the blade 5 has a cutting edge 5a that is in particular, rectilinear. If there is more than one support 3, as shown for example in
In an additional variant embodiment, also not illustrated, the blade 5 may have a circular cutting edge 5a and be a rotating blade.
Furthermore, the present invention may be applied to any other slicing machine provided with any embodiment of a cutting blade.
Advantageously, the slicing machine 1 further comprises means for adjusting 17 the distance between the blade 5 and the striking surface 4.
Note that the support 3 cited above is movable with respect to the blade 5, particularly toward and away from the blade 5, so as to pull the piece of meat 18 to be sliced against the blade 5 in a forward stroke and to bring the piece of meat 18 back to an initial position preceding the cutting, in a return stroke. In further detail, the support 3 for the meat 18 is movable along a feed direction “A”. With reference particularly to
With reference particularly to
The support 3 further comprises a pusher member 16 insertable at least in part into the compartment 13, and in particular, facing the striking surface 4 so as to push the meat 18 against it.
In yet further detail, the compartment 13 has an additional opening 15 opposite the opening 14. During operation, the pusher member 16 is inserted into the compartment through this additional opening 15, and it pushes the meat 18 towards the opening 14 in such a manner as to block it firmly against the striking surface 4.
With reference particularly to
According to the present invention, the striking surface 4 is movable relative to the blade 5. More specifically, the striking surface 4 slides along a sliding direction “B” parallel to the feed direction “A” of the support. Furthermore, the striking surface 3 slides at a speed that is substantially equal to the speed of movement of the support 3. Advantageously, in this manner the striking surface 3 maintains contact with the slice 19 of meat 18 without scraping taking place.
Specifically, the striking surface 4 slides towards and away, with respect to the blade 5, in such a manner as to cooperate with the support 3 so as to bring the piece of meat 18 against the blade 5, particularly at the cutting edge 5a thereof.
In further detail, the striking surface 4 moves alternatively between a preparation position, in which the striking surface 4 and the support 3 move a piece of meat 18 away from the blade 5, and a cutting position, in which the striking surface 4 and the support 3 push the piece of meat 18 against said blade 5 in order to cut a slice 19.
The slicing machine 1 further comprises a conveyor belt 6 connected to the frame 2, and in particular arranged between two rollers 7. In particular, this conveyor belt 6 faces the support 3, in such a manner that the piece of meat 18 rests against a portion 6a of the conveyor belt 6. Note that, according to the present invention, the striking surface 4 proves to be defined on the conveyor belt 6, particularly at the portion 6a thereof.
Advantageously, one end 6b of the conveyor belt 6 can be associated with a packaging machine (unillustrated) so as to package the slices 19 of meat 18 exiting the slicing machine 1.
In detail, the conveyor belt 6 is functionally associated with the support 3, and moves together with it. In particular, the slicing machine 1 comprises movement means 8 of the conveyor belt 6, acting on the conveyor belt in such a manner so as to synchronize movement with the previously cited support 3. In detail, the movement means 8 of the conveyor belt 6 comprises a motor 9 that is preferably electric. A drive belt 10 is operatively arranged between the motor 9 and one of the rollers 7, so as to transmit motive power from the motor 9 to the conveyor belt 6, and consequently, determine the sliding of the striking surface 4 described above.
The slicing machine 1 further comprises a carriage 11 associated with the frame 2. In detail, this carriage 11 is constrained to the frame 2 in such a manner as to slide relative thereto, in particular along tracks 12 fixed to the frame 2 and arranged along the feed direction “A” of the support 3. Moreover, the slicing machine 1 comprises movement means (not illustrated) of the carriage 11, capable of translating this carriage 11 along the tracks 12 and, as a result, moving the support 3 jointly with the carriage 11.
Note that the previously described support 3 is connected to the carriage 11, in such a manner as to be pulled by the carriage 11 along the cited feed direction “A”. As illustrated particularly in
According to the present invention, the slicing machine 1 also comprises a control unit (not illustrated) that acts upon the movement means 8 of the belt 6 and upon the movement means of the carriage 11. This control unit has the function of coordinating the movement of the support 3, particularly of the carriage 11, with the sliding of the striking surface 4.
The slicing machine 1 according to the present invention can be integrated in an apparatus for the processing and packaging of fresh meats. In addition to the slicing machine 1, this apparatus comprises a packaging machine (not illustrated) to package the slices 19 of meat 18 exiting the slicing machine 1. In particular, one end 6b of the conveyor belt 6 faces the packaging machine, so as to feed it slices 19 of meat 18 cut by the slicing machine 1.
The present invention achieves the proposed aim. The striking surface for the meat is also movable relative to the blade, particularly along a direction that is parallel to the feed direction of the support. For this reason, the meat is not ruined by scraping against this striking surface during the cutting procedure. As a result, it is no longer necessary to freeze the meat before slicing it.
The present invention also has an important advantage. In fact, as the meat does not scrape against the striking surface, no friction phenomena take place, which could otherwise overheat the meat, thus altering its organoleptic proprieties.
